Description
One, technical field
The utility model relates to a kind of stay cable end seal protection structure form; especially a kind of bitter end multilayer does not have the step-down of filling hermetically-sealed construction, is mainly used in cable stayed bridge, suspension bridge; in, the end sealing of the rope member of lower bearing arch bridge and other structures, belong to bridge construction part technical field.
Two, background technology
Drag-line is the main supporting member of cable stayed bridge, suspension bridge, arch bridge, and its safety is directly connected to the safety of bridge.The corrosion of drag-line mainly is the corrosion of anchored end, badly influences the application life of drag-line, jeopardizes Structure Safety for Bridge.The bitter end sealing is particularly important.Although Cable Structure has been taked the sealing system that stressed steel are zinc-plated, fill multiple safeguard procedures such as antirust grease, outer wrapping high-density polyethylene plastics, in the hope of the generation that prevents to corrode, but it seems, and not exclusively success from the actual conditions of a large amount of Cable Structure bridge operation observations.Do not reach design service life toward contact and just begin to occur disease, must change rope in advance.
The end sealing of existing drag-line is mainly to pour into to the neck of connecting cylinder with filler solidifies or bifilar part Polyurethane filling tube neck rubber seal water blockoff together.This mode can better must seal under static state.But in hanging the rope work progress, the easy blocked formation ponding of spilled water hole in the cable guide pipe, and drag-line when built-in shock absorber is not installed, vibrate bigger, so drag-line be in for a long period of time vibrate and the deep water soaking state under, immersion may appear in the bitter end sealing ring, thereby causes steel wire and ground tackle corrosion.So being necessary to design a kind of bitter end seals fully, especially the reliable structure of dynamic seal (packing) makes that drag-line its end sealing during construction and operation is effective.
Three, summary of the invention
The utility model provides a kind of reliable structure, make construction and operation during stay cable end sealing can effectively stop rainwater, especially conduit inner product water intrusion cable body inside causes steel wire and ground tackle corrosion.The step-down of stay cable end multilayer does not have the filling hermetically-sealed construction, adopts multilayer step-down sealing, and skin is a movable sealing structure, is that pressure and the protection internal layer hermetically-sealed construction that reduces ponding is not destroyed; The internal layer hermetically-sealed construction is to utilize a kind of flexibility, corrosion-resistant aging-resistant material, is the static sealing structure with stay cable end by the dynamic seal (packing) Structure Conversion, and its sealing technology difficulty is reduced; Again these flexible material two ends are connected sealing with drag-line HDPE sheath respectively with connecting cylinder, under the situation of vibration, also can guarantee bitter end reliable sealing problem thereby solved drag-line.
Technical scheme that the purpose of this utility model adopts is, comprise that many zinc-coated wires or steel strand pass through locating ring successively, the anchor cup, anchor slab, anchor cup end device has shrouding, the cup outer wall is with the anchor circle, its described galvanized steel tow has the HDPE sheath outward, outside the HDPE sheath, be with end cap successively, the O RunddichtringO, seal retainer ring, the flexible sealing conduit, locating ring is with connecting cylinder outward, the HDPE sheath is boss or groove and does not hold and have flexible sealing conduit one end that tightens up ring and be connected, screw passes the hole and the connecting cylinder stomidium screw-threaded engagement of flexible sealing conduit other end flange, connecting cylinder external screw thread and the engagement of anchor cup internal thread are at end cap, the O RunddichtringO, seal retainer ring, connecting cylinder is with sleeve outward.
The utility model scribbles airtight and watertight padding between described connecting cylinder and the anchor cup.
The utility model, described HDPE sheath is boss or groove is not held and the flexible sealing conduit between scribble airtight and watertight padding.
The utility model scribbles airtight and watertight padding between described connecting cylinder end face and the flange.
The utility model scribbles airtight and watertight padding between described sleeve two ends and end cap, O RunddichtringO, seal retainer ring, the connecting cylinder.
The utility model, described sleeve two ends internal thread mesh with end cap external screw thread, connecting cylinder external screw thread respectively.
The utility model by the flexible sealing pipe with cable body steel wire or steel strand and extraneously fully isolate, and at termination employing multilayer step-down hermetically-sealed construction, movable sealing is converted to static seal, reduced the protection difficulty, and increased bitter end protection reliability greatly, can solve well during hanging rope construction and operation because conduit inner product water pressure and cable body vibration make moisture immerse bitter end anchoring position, cause the problem of steel wire and ground tackle corrosion, can effectively ensure the normal application life of drag-line, produce no small economic results in society.Have simple and compact for structurely, make characteristics such as easy to assembly.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional structure schematic diagram.
